يُعد تحسين المادة العضوية في التربة حجر الزاوية في الزراعة المستدامة، إذ يُعزز خصوبة التربة وبنيتها واحتباس الماء فيها. ويمكن أن يؤدي استخدام محاصيل التغطية ودورات المحاصيل المدروسة إلى زيادة مستويات المادة العضوية في التربة بشكل طبيعي من خلال إضافة الكتلة الحيوية، وتحفيز النشاط الميكروبي، والحد من التعرية. وتعزز هذه الممارسات أنظمة بيئية مرنة تدعم نمو النباتات، وتخزن الكربون، وتقلل الحاجة إلى [...]

إفرازات الجذور هي مزيج متنوع من المركبات التي تفرزها جذور النباتات في التربة المحيطة. تلعب دورًا محوريًا في تشكيل بيئة التربة وتؤثر بشكل مباشر على توافر العناصر الغذائية. بفهم كيفية تفاعل هذه الإفرازات مع مغذيات التربة والكائنات الدقيقة، يمكننا تقدير تأثيرها بشكل أفضل على نمو النبات وخصوبته والنظام البيئي.

A funny thirty-second ad is not usually the kind of thing that drags CEOs into public arguments. But AI is not a normal product category, and the companies building chatbots are not operating in a normal competitive environment. That’s why a set of satirical Super Bowl commercials from Anthropic — the maker of the Claude

The UK’s research system runs on a simple bargain: the public funds science and innovation at scale, and in return the country gets new knowledge, new industries, and a steady stream of capability that strengthens everything from healthcare to energy to national security. This week, that bargain is under stress. UK Research and Innovation (UKRI)

JLab’s new Bluetooth speaker doubles as supersized headphones: what JLab’s Blue XL says about the next wave of personal audio JLab has built its reputation on small, practical audio gear — earbuds you can toss in a pocket, over-ears that don’t ask for a second mortgage, and controls that are more “good enough” than fussy

After a federal judge ruled that Meta isn’t an illegal monopolist in the Federal Trade Commission’s long-running case, the FTC announced it will appeal. That sounds like a procedural footnote — agencies appeal losses all the time — but this one matters because it sits at the crossroads of (1) how courts define markets in

One of the stranger incentives in modern tech policy is the research paradox: the companies that do the most internal work to measure harms can end up looking like the worst actors, simply because they have the most data — and because that data can leak, be subpoenaed, or be unsealed in court. That paradox

A headline like “sixteen AI agents built a C compiler” sounds like either a magic trick or the start of a sci‑fi plot. In reality, it’s something more interesting: a glimpse of how software engineering is changing when you can treat an AI model not as a chat partner, but as a workforce — a

Self-driving systems live and die by one question: what happens next? Sensors tell an autonomous vehicle what the world looks like right now — camera frames, lidar point clouds, radar reflections, GPS and IMU measurements. But safe driving is anticipation: predicting how pedestrians might move, whether a cyclist will merge, how a car might drift
